T0. all whom it may concern: Be itknown that I, Econ; Wooos MIX, acitizen of the United States, residing at Paris,.,Fra-nce, have inventedcertain new 5' and useful Improvements in- Guide-Bearings, of which thefollowing is a specification;

The invention relates to bearin s used more particularly to guide orstead y a ro- 10'1 tating vertical shaft and the object thereof theprovision of a bearing which. is

readily assembled and dismounted, which maybe finely or closely adjustedand which.

also prevents vibration of the shaft. 15

.1 is a top view of the bearing with the shaft shown. in section on theline 11, Fig. 2, "and the cover-removedyFig, 2 is a vertical section ofthe bearing; Fig. 3 is an exagge'rated diagrammatic view showing therelation between the shaft and bearing and the. inanner of adjustingthis relation; and Fig. 4 is a 'perspective view of the bearing rings,shown separated from each other.

"The bearing is adaptedfor use in-gener ators, turbines and a variety ofother machines. f

Mounted on the frame '1, of the machine are-three adjusting screws 2equally spaced about the axisfof the shaft 3 and provided with suitablelockingnuts to secure them in their adjusted positions. The ends ofthese screws engage the periphery of the flange 4 on the bearing 5 whichis secured in its adjusted position on the frame, by "bolts or studs 6;The holes in the flange which receive the bod portion of the bolts aremade sufficiently argerthan the bolts vto permit the necessary range ofadjustment when centering screws 2. v The bearing 5. is provided with acap 7 which is held in place by bolts 8. The 1nterior of the bearing andcap is bored out to receive three eccentric ring's9 10 and 11 which arepreferably made in halves, the

halves being secured together .in any suit- I able manner. The centersof the circular recesses which receive the rings are eccentric t'o-theaxis of the shaft 3 and are equally -spaced about the axis, that 1s the-?cj ente'r s are 120 apart, as indicated in Fig.'

73%, I'flle ring 10is provided with a gear.

The worm issecured toa shaft 14 suitably mounted in .bearingsl15 upon the flange 4. Somemeans forvactuat mg the shaft 14 is located ata place which Other isconvenient for the attendant. forms of gearing can be substituted forthewor'm gearin if desired. The 'ring'lO is provided wi wa 's or slots inthe rings 9 and 11.-

keys 16 which engage keyetween the rings 9, 10 andll-and the shaft areball'bearin s 17 18 and 19. These bearings comprise ba lrace-rings 20carried by the shaft and cooperating ball races.

rings 21 secured to, the rings 9, 1O and'll.

The ball race-rings 21 are preferably made in halves for convenience'inassembling and removing the .bearin parts'and the halves are securedtogether n any suitable manner.

Each set of ballrace ringscontains a series of balls 22 which arekept-in proper engagement by a spring .23.

Attached to the shaftabove the ball bearings is a collar 24 having aflange 25. A

casing or cover 26 is seclii ed'totheto of the bearing '5 and provided.with an internal flange 27 which projects beneath the flange 25' andalso with another flange 28 which.

surrounds the top of the flange 25, thus forming an oil-receivingchamber 29 within the, casing. One' or more oil ducts 30 lead fromtheoutside .of the cover 26 to "a point over the balls 22. Pipes 31 conductlubricant from any suitable'source to these ducts.

Attached tothe shaft at the bottom of the ball bearin s is anoil thrower32 for throwing the lubricant passing downward; from the bearing outwardinto thecha'nnelsor grooves'33 formed in the, lower part; of the earinaudits cap, thus 'preventingany oil from flowing down the shaft to be,wasted or to damage apparatus located .below'the bearing. The grooves orchannels '33are 'connected at intervals and 'a drain 34 eon-u ductslubricant away from the bearing. Any lubricant which works upward 1sthrown outward by the flange 25 into the I chamber 29 which is connectedto oneof-the rooves 33 by a drain ines,Fig.2.- j By turning the shaft 14and its worm 13, the three eccentric rings 9, E10 and "11 fare 35 shownin d'otted turned in unison in the eccentrically located totake up.practice y all refit-he tween the shaft and the bearings? eahovementioned paints and do away with the vi-;
